Question 2 What is the slope and Y intercept for the following equation? 2x - 4y = 8 A. m=2 yint = 1/2 B. m= -1/2 yint = 2 C. m= -2 yint = -1/2 D. m= 1/2 yint = -2 D CA

Answer 1

the equation is of the form y = mx + b, where m = slope and y-intercept = b, in this case

`\begin{gathered} 2x-4y=8 \\ x-2y=4 \\ x-2y-x=4-x \\ -2y=4-x \\ -(2y)/(-2)=(4)/(-2)-(x)/(-2) \\ y=-2+(1)/(2)x \\ y=(1)/(2)x-2 \end{gathered}`

answer:

m = 1/2

y intercept = -2
